To determine whether, similar to adults, early tracheostomy in pediatric patients with severe traumatic brain injury (TBI) improves inhospital outcomes including ventilator days, intensive care unit (ICU) length of stay (LOS), and total hospital LOS when compared to late tracheostomy.Retrospective cohort analysis.The Pediatric Trauma Quality Improvement Program (TQIP) database.One hundred twenty-seven pediatric patients <16 years old with severe (>3) abbreviated injury scale TBI who underwent early (days 1-6) or late (day ≥7) tracheostomy between 2014 and 2016.Not applicable.The Pediatric TQIP database was queried for patients <16 years old with severe TBI, who underwent tracheostomy. Patient demographics and outcomes of early versus late tracheostomy were compared using Student t test, Mann-Whitney U test, and χ2 analysis. Sixteen patients underwent early tracheostomy while 111 underwent late tracheostomy. The groups had similar distributions of age, gender, mechanism of injury, and mean injury severity scores (P > .05). Early tracheostomy was associated with decreased ICU LOS (early: 17 vs late: 32 days, P < .05) and ventilator days (early: 9.7 vs late: 27.1 days, P < .05). There was no difference in total LOS (early: 26.7 vs late: 41.3 days, P = .06), the incidence of acute respiratory distress syndrome (early: 6.3% vs late: 2.7%, P = .45), pneumonia (early: 12.5% vs late: 29.7%, P = .15), or mortality (early: 0% vs late: 2%, P = .588) between the 2 groups.Similar to adults, early tracheostomy in pediatric patients with severe TBI is associated with decreased ICU LOS and ventilator days. Future prospective trials are needed to confirm these findings.Early tracheostomy in pediatric patients with severe TBI is associated with decreased ICU LOS and ventilator days.
Methods: Variables including height, density, number of flowers and species richness were recorded on three different days; October 2nd, 9th and 16th 2014. The species chosen to be the objective of the study was White Aster (Symphyotrichum ericoides). The data was collected in a power line corridor located across York University north of Steeles Avenue West (43.779291, -79.504367). A drainage ditch in the corridor was chosen as a form of water supply, located as a divider between the grassland and surrounding buildings on Steeles Avenue. Quadrat sets of 1m x 1m were recorded along the drainage ditch at three different distances. The quadrats were placed at three distances, each 1.5 meters parallel along the transect going perpendicular to the water supply. The primary set of quadrats were placed at 0 meters from the edge of water supply, the secondary set was placed at 10 meters from the edge of the first quadrats and the tertiary set was placed at 20 meters from the primary quadrats location. The height of White Aster (S.ericoides) individuals was recorded in meters from the base of the stalk to the tip of the flowers using a transect. This procedure was repeated for all individuals in each of the quadrats. The numbers of different plant species were recorded to account for species richness within each quadrat. The density of White Asters was visually estimated in each quadrat and recorded as a percentage value. The numbers of flowers for each individual Aster plant stem were recorded in each quadrat; only the flowers that were fully bloomed were included in the visual number count. A total number of 21 quadrats were used for the collection of data, which will be analyzed using bar graphs with standard deviation bars. The average value and standard deviation of each variable will then be plotted against the distance from the water source. One-way ANOVA analysis with a=0.05 will be used to test the variance within the collected variables in relation to the distance from the water supply.
Captopril renography is used for the non-invasive diagnosis of renovascular hypertension, but suffers from the drawbacks of lower sensitivity and false-positive tests due to a fall in blood pressure. Aspirin renography has been proposed as a useful test for evaluation of unilateral renal artery stenoses of moderate degree. We studied the clinical usefulness of aspirin renography in 12 patients with a clinical suspicion of renovascular hypertension and compared it with captopril renography using 99Tcm-DTPA. The test was considered positive if there were changes in the time-activity curve according to the criteria specified by the American Society of Hypertension Working Group. Four patients with discordant results between captopril and aspirin underwent intra-arterial digital substraction angiography. In two patients, the renal arteries were normal; captopril was false-positive in both these patients. Bilateral stenosis was noted in the third patient, with captopril being false-negative on the right side with moderate stenosis, whereas aspirin was true-positive. There was unilateral stenosis in the fourth patient; captopril was false-positive on the contralateral side. Our results suggest that aspirin renography is superior to captopril renography in the assessment of patients with a suspicion of both unilateral and bilateral renovascular hypertension.
Traumatic esophageal injury is a highly lethal but rare injury with minimal data in the trauma population. We sought to provide a descriptive analysis of esophageal trauma (ET) to identify the incidence, associated injuries, interventions, and outcomes. We hypothesized that blunt trauma is associated with higher risk of death than penetrating trauma. The Trauma Quality Improvement Program (2010–2016) was queried for patients with ET. Patients with blunt and penetrating trauma were compared using chi-square and Mann-Whitney U tests. A multivariable logistic regression model was used to determine risk of mortality. Of 1,403,466 adult patients, 651 (<0.01%) presented with ET. The most common associated thoracic injuries were rib fractures (38.7%) and pneumothorax (26.7%). More patients with a penetrating mechanism underwent open repair of the esophagus than those with blunt mechanism (46.2% vs 11.7%, P < 0.001). After controlling for covariates, there was no difference in risk of mortality between blunt and penetrating trauma ( P = 0.65). The mortality rate for patients with esophageal injury surviving greater than 24 hours was 7.5 per cent. In this large national database analysis, ET was rare and most commonly associated with rib fractures and pneumothorax. Contrary to our hypothesis, the risk of mortality was equivalent between blunt and penetrating ET.
Studies demonstrate a significant variation in decision-making regarding withdrawal of life-sustaining treatment (WLST) practices for patients with severe traumatic brain injury (TBI). We investigated risk factors associated with WLST in severe TBI. We hypothesized age ≥65 years would be an independent risk factor. In addition, we compared survivors with patients who died in hospital after WLST to identify potential factors associated with in-hospital mortality. The Trauma Quality Improvement Program (2010–2016) was queried for patients with severe TBI of the head. Patients were compared by age (age < 65 and age ≥ 65 years) and survival after WLST (survivors versus non-survivors) at hospitalization discharge. A multivariable logistic regression model was used for analysis. From 1,403,466 trauma admissions, 328,588 (23.4%) patients had severe TBI. Age ≥ 65 years was associated with increased WLST (odds ratio: 1.76, confidence interval: 1.59–1.94, P < 0.001), whereas nonwhite race was associated with decreased WLST (odds ratio: 0.60, confidence interval: 0.55–0.65, P < 0.001). Compared with non-survivors of WLST, survivors were older (74 vs 61 years, P < 0.001) and more likely to have comorbidities such as hypertension (57% vs 38.5%, P < 0.001). Age ≥ 65 years was an independent risk factor for WLST, and nonwhite race was associated with decreased WLST. Patients surviving until discharge after WLST decision were older (≥74 years) and had multiple comorbidities.
